ISAACA HAYES, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVED WATER-WHEEL.

Specitcatipn forming part of Letters Patent No. 35,822, dated July 8, 1862.

'declare that the following is a full, clear, and

exact description of the construction and op eration of the same, reference beinghad to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective View, Fig. 2 a sectional plan view, and Fig. 3 a vertical centrai section, of the said improved wheel.

Like letters indicate the same parts when in the different figures.

My invention relates, particularly, to the hydraulicwheel known as Barkers Mill;.7 and it consists in conducting the wat-er through asupply-pipe leading from the head of the water-power to the upper end of the wheel, and then in spiral directions downward through the said wheel to the discharge orices at its circumference by means of a series of tapering spiral tubes, in combination with a central chamber fixed to the shaft of the wheel and attached to the said supply-pipe, as hereinafter described, for the purpose of increasing the effective power of the said Barkers wheel.

In the drawings, A A A are the tapering spiral tubes; B, the shaft; C, the central` cham'- ber, and D the supply-pipe. The tapering tubes A are in this instance three in number, and are each permanently secured to the bottom of the central chamber, C, so as to open into the saine, as seen in Fig. 3, and extend therefrom downward in distinct and continualiy-.enlargingspiral directions to ih eir mouths, as seen in Figs. l and 2, thus providing t'or the discharge of their respective proportions y ot' water in directions tangential to the circumference of the` wheel.

The central chamber, C, is attached to the lsupply-pipe D by means of a collar, d', which incloses a flange, (Z2, on the pipe, and screws pipe D into such connection with the upper end ofthe chamber C, with packing between,

if required, as will allow the latter to rotate,

and at the same time produce a nearly watertight joint between the said pipe and chamber, substantially as seen in Fig. 3.

The supply-pipe D is intended to be continued up to the head of the water-power, and

secured in a fixed and steady position aboveV the wheel by means of three or more supports,

E E E, which rest upon the platform F below the wheel, as seen in Fig. l, or in any sufficiently strong and steady manner.

The upper end of the shaft B is fixed in the center of the bottom of the chamber C, while its lower end rests in a socket, G, which is fixed to the piatforin F, and thus the wheel is supported so that it may be rotated in the vertical position seen in Fig. l. y

Near the lower end of the shaft B a bevel-v pinion, H, is fixed, which gears into a bevelwheel, I, xed upon a horizont-al shaft, i', that is intended to connect with any other gearing suitable for the purpose of transmitting the power of the wheel.

In the operation of this improved wheel the peculiar form and arrangement of the tubes A favor both the delivery of the wateraiid. the recoil ofthe wheel, and they being connected with the supply-pipe D byv means of the central chamber, C, there is no liability to an overflow of water upon the wheel, while the latter has at the same time the advantage of the Whole weight of the colninnof water from its head to the orifices of the wheel, an important feature, as these wheels are intended for small streams with high heads.

Having thus fully described my improvement in Barkers wheels, what I claim as new therein, of my invention, and desire to secure by Let-ters Patent, is-

The employment of the tapering spiral tubes A A A, in combination with the central chamber, C, and continuous supply-pipe D, the same being arranged to operate together in the manner described, and for thepurpose specified.
